Shevchuk S. Improvement of reclaimed area on the basis of the informational and analytic system of ecological and land-reclamation monitoring

As the result of analysis of current state and operating of reclaimed area it has been determined the decision making expediency on the basis of the informational and analytic system of ecological and land-reclamation monitoring and GIS technologies that allows to increase the quality and efficiency of technological, ecological and economical management problems solving in regard to land and water use.It has been worked out the scientific principles, methods for development of model and bundled software of informational and analytic system of change of state processes analysis and rational (ecological, technological, economical) decision making for management problems of reclaimed area. It has been created the scientific foundation and methods for GIS elaboration of hydrogeological modelling for the task solutions of space-time modelling of hydrodynamic processes at determination of a time history of area state, flooded and underflooded zones within reclaimed land.The informational and analytic systemhas been used for investigation of change of state processes at the targets of flooding and underflooding on reclaimed area (by the example of Kherson region). It was worked out the set of technological constraints in regard to irrigation regimes, water application and irrigation rates at land use in different underflooding risk zones for the land and water use management, ecological and economical problems solving.On the basis of the informational and analytic system it is determined the warning and elimination measures for underflooding and surface flooding events on reclaimed area.
